The faster a
network, the more rapidly it sends a file from one computer to another.
Networking speeds are measured in megabits per second (Mbps). Standard
Ethernet transmits data at a speed of 10 Mbps, which is ample performance
to send business files quickly to other computers and printers.
Fast Ethernet is
identical to Ethernet, only ten times faster at 100 Mbps. A single LAN can
support both Ethernet and Fast Ethernet connections.

When building your
first network, consider that although your organization may not require
the additional performance of Fast Ethernet now, it may in the future as
it deploys more sophisticated applications and grows its workforce. For
this reason, build with an eye to the future.
Which speed is
right for you?
Select the
additional performance of Fast Ethernet if you work with large files like
graphic and databases or if you have 10-15 or more users on the network.
However, even if your present networking needs are modest, your business
may grow over time and your applications may expand in size. As a result,
the demands placed on your network will increase and you’ll need to
migrate to Fast Ethernet speed. You can either build the network on Fast
Ethernet or upgrade it over time. To upgrade an Ethernet network to Fast
Ethernet, you need to deploy: 100 Mbps switches or hubs; NICs (network
interface cards), which are cards that fit into each computer and
determine how fast the device links to the network; and Fast
Ethernet-capable cabling.

When upgrading your
network to Fast Ethernet, replacing a switch or hub is relatively easy;
replacing the NICs in every computer is time-consuming and installing new
high-speed cabling can be costly. For your first network, we recommend
that you deploy dual-speed NICs, which will automatically link each
computer at Ethernet speed to a 10 Mbps switch or hub, or Fast Ethernet if
the switch or hub is capable of 100 Mbps. Additionally, deploy Cat-5
cabling in your office from the onset. This grade of cabling supports both
Ethernet and Fast Ethernet networks. By deploying dual-speed NICs and
Cat-5 cabling, you can upgrade your network to Fast Ethernet simply by
installing a 100 Mbps switch or hub when the need arises.

Of course, by
deploying Fast Ethernet now, you future-proof your network and protect
your investment. If you deploy a dual-speed switch, or hub, and dual-speed
NICs, linked by Category 5 cabling, your network will operate at
high-speed 100 Mbps Fast Ethernet, ensuring rapid communications and ample
performance for future expansion.
